Kerberos authentication is a network protocol that secures user access to services/applications by using secret-key cryptography across client-server communications. The Kerberos network authentication protocol helps prevent hackers from intercepting passwords over unsecured networks.
A data exfiltration attack involves the unauthorized transfer of sensitive data, such as personal data and intellectual property, out of a target system and into a separate location. These transfers could either occur internally, through insider threats, or externally, through remote Command and Control servers. Every cyberattack with a data theft objective could be classified as a data exfiltration attack.
The combination of poor cybersecurity practices, sensitive data storage, and a desperation to preserve business continuity at all costs, makes the healthcare industry a prime target for cybercriminals - an inevitability that was further exacerbated by the pandemic. To support the relevance of healthcare cybersecurity programs within the current cyberattack climate, the 4 biggest cybersecurity challenges in the healthcare industry are listed below.
CIFS (Common Internet File System) is a network protocol that allows clients to communicate with servers and access file sharing and print services as if they were stored locally. The CIFS protocol is a particular implementation -- or dialect-- of the file-sharing protocol SMB (Server Message Block). The Server Message Block protocol was released by IBM in 1983 that has since undergone several modifications to its functionality by Microsoft.
CIFS and SMB are both Windows file-sharing protocols used in storage systems, such as network-attached systems (NAS). The key difference between CIFS and SMB is that CIFS is a dialect of SMB – a particular implementation of the SMB protocol. The CIFS protocol is now considered an outdated SMB dialect, with the newer SMB 2.0 and SMB 3.0 addressing many of the inefficiencies of CIFS.
As cybersecurity regulations continue to tighten their grip on vendor security, a greater weight of responsibility is expected to fall on Third-Party Risk Management Programs. So if you're currently struggling to keep up with your vendor security due diligence, your workflow congestion will only worsen if a scalable and streamline vendor risk management program isn't achieved.
It's easy for cybersecurity teams to think they're doing everything to stay ahead of data breaches and cyberattacks in this post-pandemic era. For instance, you've probably rallied qualified experts to augment your IT ecosystem and supplied them with state-of-the-art threat detection and mitigation technologies that offer real-time insight into your infrastructure security.
The open ports in your hardware could be critical points of vulnerability if the services exposed to them are misconfigured or unpatched. Unfortunately, many organizations are currently exposing their sensitive resources through such malicious connections, heightening the risk of ransomware attacks, supply chain attacks, and data breaches.
A security questionnaire is a set of questions designed to help an organization identify potential cybersecurity weaknesses among its third-party and fourth-party vendors, business partners, and service providers. Organizations use security questionnaires to deliver informed vendor risk assessments. They allow organizations to vet potential vendors and other third parties by ensuring their information security practices and security policies meet both internal and external requirements.
A reverse Proxy server processes all traffic between end-users and a web server. To achieve this, this type of proxy server is situated at a network's edge as an additional endpoint where it receives all initial HTTP connection requests before they're sent to the origin server (where all website data is stored). Reverse proxies can be regarded as the security guard of your network, ensuring all connection requests are legitimate and securely established.
